If you wish to create a website, you need 2 things - a domain name and a hosting plan for it. The domain registration is the actual web address that you type in a browser to access a website, while the hosting space is where your site files is going to be. These are two very closely related, yet individual services, even though many people believe that registering the domain is enough. Similar to the disk space and the monthly traffic features which a given hosting plan offers, there are a certain number of registered domain names that you can include as hosted which means that you can have the web content for them in some account even if the domains are actually registered through a different service provider. In technical terms, it doesn't matter whether a domain is registered and hosted with the same company or is registered with one company and pointed to another one - in either case your websites will operate the very same way.
